If I lower the vertical amp it gets more crazy and leaves the display. Should I try a different us setting?
If you probe isn't set to 10x, set it to 10x and try again.
If I set the scope to 10v/d and 50us this is what I get at max volume. Is this a clipped signal? Both channels perform identical no matter the setting.........Thoughts???

Yes. Set the timebase to show 3-4 complete cycles. Try adjusting the trigger level to get it to trigger properly. Unless you're using two probes/inputs, it should only have one waveform.
Whenever using the scope, unless you have a good reason to do otherwise, adjust the timebase to display 3-4 complete cycles. Set the vertical amp so that the waveform is deflected between 2 major divisions and 4 major divisions (the top of the graticule).
If both channels perform the same with a load, it's not likely a driver issue.
Are you sure that you don't have an intermittent connection on any of the components between from the drivers to the gates of the output transistors?

That was a 100Hz test tone. Any suggestions on what I may be doing wrong? Have not got the bananna clip yet, think my scope ground isn't connecting good?
Ok Perry think I have what you want.
Scope settings:
20 vol/div
1 ms
100hz test tone
first pic is 1/2 volume 15
second pic is 3/4 volume 25
Is this the clip signal you wanted to see?
Both channels perform identically.

That's clipping.
The drivers are all likely OK if both channels clip like that.
Where did you buy the outputs?

I bought them from a seller on ebay. I have repaired probably 75 amps with these drivers without an issue. Not saying I didnt get a few bad in the batch though. Is it always pertinant to use the same date code in both channels?
The channels don't have the have matching date codes. Only parallel outputs need to match.
I don't understand the Question in post #36.

I just read in a few of your posts, and remeber something about you saying to make sure the date codes match. I could be mistaken, sorry for any confusion........Its almost 4am here need sleep sorry. TTYS
So if its not a driver issue, where do I go from there. I have never had an amp do this before so Im a little lost.
Wondering where I should go next? Its like the squaling stays for a few seconds, draws some current then you hear a pulse like the amp is turning on and it goes away. It makes the same sound when you disconnect the remote wire but only for a second. Almost like a screech. Only the one channel does it though. I must me getting some serious feedback for a few seconds somehow, just not sure. Maybe the IN4003's ? Is there a way to check the rca ground shield other than a wiggle test?
